9. Question:
Why does the drill bit back up into the Chuck during
the sharpening procedure?
Answer:
Make sure the bit is tight in the Chuck before sharpening.
Your Chuck may be dirty. Follow the steps for cleaning the
Chuck on page 24.
10. Question:
When splitting, why don’t I hear a grinding sound?
Answer:
The Chuck is not seated properly in the Splitting Port. The
Chuck’s Sharpening Guide must line up with the Splitting
Guide on the top of the Split Point Port. Firmly and slowly
push the Chuck into the hole until the grinding sound stops.
11. Question:
Can I change a 135° drill bit into a 118° drill bit?
Answer:
You can change the degree angle of any drill bit from 135°
to 118°. The alignment and sharpening procedure will
need to be performed three or more times to remove the
old angle and produce the new angle desired. If you
change a 135° angle to a 118° angle you will not be able to
return to a 135° angle using this machine.
6. Question:
Why is the chisel edge on my drill bit flat?
Answer:
During the alignment process the Bit Clamp Arms were
gripping the high points of the drill bit. Realign the drill
bit making sure that the Bit Clamp Arms are located in the
narrowest section of the bit.
7. Question:
Why was my drill bit sharpened improperly?
Answer:
The most common cause of improper sharpening is
improper drill bit alignment.
Key causes are:
1. Drill point not pushed all the way to the Drill Stop.
2. Chuck not pushed all the way into the Alignment Port.
3. Drill not aligned in the Bit Clamp Arms correctly.
In order to correct these problems be sure the Chuck is all
the way in the Alignment Port. The drill point must be
against the Drill Stop and the Bit Clamp Arms must be at
the narrowest part of the drill bit.
8. Question:
Why is my split point uneven?
Answer:
Page 14 shows a drill point that is undersplit and a drill
point that is correctly split. To correct an uneven point
split, insert the Chuck into the Splitting Port and split
both sides again. Push the Chuck into the Port until it
stops. Repeat until the split sides are equal and look like
the correctly split bit shown above.
